    • Field Detail

      • processorCache

        protected int processorCache

        protected boolean directSslBuffer
        Enable/disable direct buffers for the network buffers for SSL Default value is disabled
      • rxBufSize

        protected Integer rxBufSize
        Socket receive buffer size in bytes (SO_RCVBUF). JVM default used if not set.
      • txBufSize

        protected Integer txBufSize

      • appReadBufSize

        protected int appReadBufSize
        The application read buffer size in bytes. Default value is rxBufSize

      • bufferPool

        protected int bufferPool
        NioChannel pool size for the endpoint, this value is how many channels -1 means unlimited cached, 0 means no cache, -2 means bufferPoolSize will be used Default value is -2
